DEVICE USED IN MOLDING WALLS.

Specication of Letters Patent.

Patented Nov. 9, 1915.

Application filed November 24, 1914. Serial No. 873,706.

To all lwhom t may concern Be it known that I, JOSEPH S. AMBRosE, a citizen of theUnited States, and a resident of Prescott, in the county of Yavapai and State of Arizona, have invented a new and Improved Device Used in Molding Walls, of which the following is a full, clear, and exact description.

My invention has for its object to provide a device used in molding a wall with openings which, in each course are staggered relatively to the openings in the adjacent courses so that a transverse tie will be disposed above and below each opening.

In constructing the wall I use side and end frames which are detachably secured together, the openings being formed by cores, the ends of which are supportedby plates which also serve to support the transverse tie sections until they set, the said transverse tie sections being disposed as stated over the openings in the course therebelow.

The cores are constructed with sides having ends, the inner sides of which converge outwardly so that when the end pieces are moved outwardly by means provided, they will force and hold the sides apart, it being possible to draw the end pieces toward each other to free the cores from the wall.

Additional objects of the invention will appear in the following 'specification in which the preferred form of my invention is disclosed.

In the drawings similar reference characters refer to similar parts in all the views in which- Figure 1 is a plan View showing the forms of molds in position and the wall in course of construction; Fig. 2 is a plan view of a wall constructed in accordance with my improvements; Fig. 3 is an enlarged longitudinal sectional view of Fig. l; and Fig. 4 is a transverse sectional view of Fig. 1.v l

By referring to the drawings it will be seen in constructing the wall I make use of side forms 5 and end frames-6, the side forms 5 having slots 7 extending downwardly and outwardly through the ends 8 of the side forms 5 for receiving the pins 9 which project from the end forms 6. In this way the end forms 6 are held in place relatively to the side forms 5, the side forms 5 being positioned relatively to each otherl by the following means. Projecting outwardly from oneof the side forms 5 there are pins 10 and projecting from the other side forms 5 there are screws 11, arms 12 being mounted on the pins 10 and being held in place by the cotter pins 13, the additional arms 14 beingmounted on the nuts 15 which mesh with the screws 11 as shown in Fig. 1 of the' drawing's. To the arms 14 there are secured the rods 16, these rods 16 lbeing disposed in the orifices 17 in the arms 12, the rods 16 being secured relatively to the arms 12 by the set screws 18. It will be understood that by turning the nuts 15 the side forms 5 having the screws 11, may be moved relatively to the companion side form 5, as may be desired. It will also be understoodthat by turning the set screws 18 the arms 12 and 14 may be moved away from each other.

The sideforms 5 and the end forms 6 are used to mold the outer surfaces of the wall, the openings in the wall being formed by the cores which have side members 19 and end members 20, the side members 19 having ends 21 with inner sides 22, these inner sides 22 converging outwardly to be engaged by the sides 23 of the end members 20, which also converge outwardly. Each of the end members 20 of the core serves as a wedge and it is provided with a screw 24', the screws 24 being substantially in alinement and being engaged by a turnbuckle 25 so that by rotating the turn-buckle 25, the end members 20 of the core may be moved to and from each other as desired. l/Vhen the end members 20 are moved away from each other, their action against the converging surfaces at the inner sides 22 of the ends of the side members 19, serve to move the side members 19 away from each other. When the turnbuckle 25 is turned to move the end members 20 of the core in the direction of each other, the side members 19 of the core are permitted vto move toward each other under the influence of the springs 26, the terminals of which are secured to the stops` 27, these stops 27 apart, the'transverse tie portions 28 of the wall will be formed and as the openings made by the molds in the next course will be positioned over the transverse tie portions 28 of the wall, it is necessary to make use of some means to support the transverse tie portions of the wall in the next course. Plates 29 and 30 are used for this purpose, the plate 29 moving against the the transverse tie portions of the wall have set.

claim as new and desire to secure by Letters Patent: y

s 1. In a,means of the class described, a core consisting of members spaced apart, ends serving as wedges movably disposed between the inner sides of the ends of the members, stops on the inner sides of the members for engagement by the said ends to limit their inner movement, and means connecting the ends for drawing them in the direction of each other.

2. In a means of the class described, a core consisting of members spaced apart, ends serving as wedges movably disposed between the `inner sides of the members, stops on the linner -sides of the members for Aengagement by the said ends to limit their inner movement, screws secured to the ends and disposed inwardly, and a turnbuckle meshing with the yscrews for the purpose specified.

3. In a means of the class described, a core consisting of members spaced apart,

Having thus described my `invention I .the members, screws secured to the ends and disposed inwardly, a turnbuckle meshing with the screws, stops yto limit the inward movement of the ends relatively to the members, and springs connecting the stops.

5. In a means of the class described, end

and side forms secured together, a core disposed within the forms and consisting of members spaced apart, ends serving as wedges movably. disposed between the ends of the members, means for moving the ends longitudinallyof the members, and collapsible plates free from the core for supporting the ends of the cores and serving as a foundation for a transverse tie wall section.

6'. In a means of the class described, a core consisting. of members spaced apart with their inner sides atl their ends converging outwardly, ends movably disposed between the converging sides of the members, screws secured to the ends and disposed inwardly, a turnbuckle meshing with the screws, stops to limit the inward movement of the ends relatively to the members, and springs connecting the stops.

In testimony whereof I have signed my name to this speciication in thefpresence of 'two subscribing witnesses.
